3. Test all people to there limits, ask them questions revolving around the case, example: Where were you at this time? Who was online with you at this time? Was anyone being suspicious or quiet at this time?)

4. Know your players, if you know your players and their backgrounds, you have a better chance or choosing the appropriate suspects.
